The waveguide allows propagation of the same fundamental mode as an optical-fiber, namely, the H E11 mode. This simple concept opens the way for corrugated wave-guides up to several terahertz, maintaining beam characteristics as for terahertz applications.American Institute of Physics0034-6748Review of Scientific InstrumentsJournal Articles10.1063/1.3597579
